Jeremiah
Jeremiah 33:14BSB·traditional attribution

Behold, the days are coming, declares the LORD, when I will fulfill the gracious promise that I have spoken to the house of Israel and the house of Judah.

John Calvin Reformed @genevareformer

Jeremiah now shews why God had promised that there would be a quiet habitation for shepherds, so that no one would by force take away their flocks. For God declares, that his promise would not be void, as its effects would shortly be evident, even when his mercy was known by the ten tribes and by the kingdom of Judah.

Matthew Henry Presbyterian @wholebiblehenry

Here is a further prediction of the happy state of Judah and Jerusalem after their glorious return out of captivity, issuing gloriously at length in the kingdom of the Messiah. I. It is promised that the people who were long in sorrow shall again be filled with joy.

John Gill Reformed Baptist @doctorgill

Behold, the days come, saith the Lord,.... Or, "are coming" (t); future times are respected; yet such as would quickly come; five or six hundred years more, and then would be fulfilled what is after promised. This is ushered in with a "behold", as being a matter of importance, and deserving attention, and even as calling for admiration.
